The hecatonicosihexacositruncated hecatonicosihexacosichoron, or hixthix, is a nonconvex uniform polychoron that consists of 600 truncated tetrahedra, 120 truncated dodecahedra, and 120 icosidodecatruncated icosidodecahedra. 1 truncated tetrahedron, 1 truncated dodecahedron, and 2 icosidodecatruncated icosidodecahedra join at each vertex.
The vertices of a hecatonicosihexacositruncated hecatonicosihexacosichoron of edge length 1 are given by all even permutations of:
